STACK-COVER.

T 0 all whom it may concern Be it known that I, GEORGE W. BoLL, a citizen of the United States, residing at l l'ichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements'in Stack-Covers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. V

This invention is a portable cover for hay, grain, or other products, to protect the some from deterioration due to exposure to rain, snow and the like, the cover being supported by, and'conforming to the outline of, the material to be protected.

"he invention embodies a sectional metallic cover which maybe rolled, or otherwise reduced to a compact space for transportation, which cover may be readily enlarged by the addition of sections thereto.

More specifically stated, the invention comprises a plurality of sections, each section having a series of metallic plat-es flexibly united, abinding element common to each pair of sections, wherebyjthe various parts may be assembled into a substantially unitary structure, and means for retaining the cover in position.

The invention consists also in the features of construction and combinations of parts hereinafter described and specified in the appended claims.

In the accompanying drawings, I have illustrated one embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a perspective view of a cover comprising two sections, illustrating the application of a cover to a stack, and the means of connecting the sections. Fig. 2 is a sectional View on the line 2-2 of Fig. 1. Fig. 3 is a sectional view through a joint between two coversections, on the line 33 of Fig. 1. Fig. 4: is a etail view showing the interlocking joints of plates composing a section. Fig. 5 is a perspective view of one of the retaining hooks. Fig. 6 is an enlarged detailed view of a hanger for a weight-member.

The structure consists of a plurality of 00- operating sections, two of which A, B, are shown in the drawing. Each section com- Specification of Letters Patent.

Application filed June 1,1912. Serial No. 7o1,1oa"- Y prises a series of interior plates 5 and end plates 6. Zihese plates may be constructed of any suitable material, but it is preferred to make them of metal which will withstand the injurious effects due to exposure to the weather. The plates are preferably made of thin or pliable metal, first, to permit the cover as a whole, or in sections, to be rolled into a compact space for storage or transportation, and, second, to adapt thecover as a shelter for material of different out- ].ines,for example, a conical stack or an oblong stack. Each plate 5 is turned upon itself, as at 7, (Figs.& and 4-) to form an outwardly hent flange along one horizontal side edge of the plate, and is also turned upon itself at- 8 to produce an inwardly bent flange along the opposite longitudinal side edge thereof. Each plate 5, therefore, is'provided with oppositely bent flanges 7, 8, the flange 7 of one plate engaging with the flange 8 of the next adjacent plate to form a weather tight oint, where they may be riveted, as shown in Fig. 2. The end plates 6 are preferably provided with the flange '7 along one side thereof only. The other side of plate 6 is provided with a clip 9 adapted to support a weight member 10, suspended by any suitable means, such as the cable 11. These weight members operate to retain the cover upon the material to be protected, and also to keep the plates 5, 6 under tension, thereby preventing the plates from becoming disengaged at the joints 7, 8. Any number of these interlocking plates 5, 6, may be employed to produce a section of greater or less width. If desired the plates may be united through the flanges 7, 8, by bolts 12, or other suitable fastening means. At each end of plates 5, 6, there is provided a bead 13 which may be formed by any suitable means, but in the drawing it is composed of a core member around which the material composing the plate is wrapped, as in Fig. 8. Each plate 5, 6, is provided, also, with a plurality of retaining members, in the form of hooks 14. Each hook 14 is preferably a flat piece of metal which is bent upon itself to form the flat hook member and the shank, said shank having any suitable means for attaching the hook to a plate, as at 15. One or more of these hooks are placed near each end of the plate, the closed end, a, of the hooks at one end of the plate 5 or 6 being preferably positioned opposite to the closed end, a, of the hooks at the other end as illustrated in Fig. 1.

In assembling the parts of the cover, the plates 5 are coupled together until a section of sufiicient length is constructed, where upon the end plates 6-, with their attached plates, are coupled to the intermediate plates 5, by means of the interlocking flanges 7, 8. The edges of sections A, B, are brought into engagement, preferably, to permit one section to overlap the other, asin' Fig. 3, thereby bringing the hooks 14 of the adjacent sections into register and permitting the bead 13 of one section to abut against the under face of the adjacent section for the purpose of producing a joint which will exclude the access ofrain, snow and the like, to the material under the cover. A rod 16 (Figs. 1 and 3) is passed into engagement with the oppositely'positioned hooks 14 of the adjoining sections A, B, where said rod operates to retain the sections and the various plates 5, 6, composing said sect-ions, into a unitary structure. If desired, the freeends of the hooks 14 may be bent down to prevent the rod 16from working out of engagement with the hook. It will be observed that the rod 16 and the bead 13 are preferably positioned out of alinement with each other (as shown in Fig. 3) whereby the rod 16 may operate to depress the overlapping end of the section, such as B, to retain the section in firm engagement with the bead 13 for the purpose of producing a firm union therewith. When it is desired to transport the cover, or to store it away, the rod 16 is disengaged from the series of hooks 14, permitting the sections A, B, as

unitary elements, to be rolled into compact form, or these sections A, B, maybe divided into smaller parts by disengaging the plates 5, 6, at the joints 7 8 thereof.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the class described, aplurality of separable sections, each comprising a plurality of plates, a plurality of opposed staggered hooks, a weather bead formed on each of said plates adapted to engage with the under face of an adjacent plat-e, said bead cooperating with said plate to produce an interiorly disposed and substantially weather tight joint, and a single binding element common to all of saidhooks to retain the bead and plat-e in' a firm contact relation.

2. In a device of the class described, a I

continuous binding element adapted to engage with all of said hooks and to be positioned out of alinement with the weather GEORGE W. BOLL, Witnesses:
